OpenCV3 Make

[blgnksy]

Hi,

My computer's setup is Ubuntu 14.04, Cuda 8, CuDNN 5 and OpenCV 3.2.0. I faced a problem while compiling compute_flow.cpp. I think after OpenCv 2.4 the gpu module had been changed to cuda module. Is there any way to compensate this issue?

Thanks.

I have the same issue and it's a bit annoying.

@pedro-abreu @jkuh626 You should change the source code and adapt to new OpenCv versions.

@blgnksy But how to adapt this to a new version, man?

[blgnksy]

@Katou2 First install the opencv. If you install a newer version than the original gpu_flow used, than search the opencv api documentation and change the includes and method names. You will see class and method prototypes have been changed.

[KT27-A]

@blgnksy Ok, Thanks a lot, man.

@blgnksy Hi, man, sorry to bother you again. I've installed opencv 3.4.3 and remake the repository again. I got such problems:

Are these you said prototypes changes? But I cannot find them in opencv documents. Have you met such problems? Thank you very much.

[blgnksy]

Yes, those are the prototypes changes. OpenCv programmers transferred some methods to another class. Whenever I have spare time, I can check and try to inform you. Can you push your codes to github repo?

[blgnksy]

Hi,

You have some not installed dependencies. https://www.learnopencv.com/install-opencv-3-4-4-on-ubuntu-16-04/ https://www.learnopencv.com/install-opencv-3-4-4-on-ubuntu-16-04/ read the page and install the dependencies.

@blgnksy https://github.com/blgnksy Thank you very much. That's so kind of you. Now I nearly find all of changes and I found that the two optical flow extraction methods are in the opencv_contrib, but I got stuck by compiling it. Do you know what happens? I searched a long time for the solution.

@blgnksy Thank you very much, man. Everything has been settled.

[blgnksy]

@Katou2 I didn't meet that problem. But it seems at least of the command line arguments that you passed is wrong. Since the error indicates the 158th line in command_line_parser of the opencv core module. Try to debug the before 136th line in compute_flow.cpp that all of the arguments are in correctly passed. Or remove that part and handle the arguments as declaring variables in compute_flow.cpp to pass that part.

[blgnksy]

@Katou2 How can you overcome that error?

[KT27-A]

@blgnksy I checked the document of Opencv detailedly, I found the keys form in the code is different from the form in the document. When I adapted it to the document, it worked.

[blgnksy]

@Katou2 Good job. I also think that the problem is about the command_line_parser of OpenCV. And I think you should push your new working codes to your repo. So If anyone meets same problem, will use your codes.

[KT27-A]

@blgnksy Yeah, that's it. Thank you very much for your help indeed.

[blgnksy]

@Katou2 No problem. Unfortunately original developers doesn't answer any issue.

[KT27-A]

@blgnksy Hah, it pushes us to fully understand what their code expresses. Not bad.

@1803643593 Hello, the prototypes changed a lot between opencv2 and opencv3. I have updated this code to opencv3, if you have interest, just go to https://github.com/Katou2/Optical_Flow_GPU_Opencv3. Hope this can help you.
